High-performance liquid chromatographic estimation of eluates from denture base polymers

Quantitative analysis of allergenic ingredients in eluate extracted from used denture base resin

“…Thus, the high‐level elution of MMA and BA observed in some of the dentures in the present study is thought to be due primarily to the influence of the self‐curing acrylic resin used in denture repair. However, as we could not precisely determine whether self‐curing resin was contained in the immersed specimens used in the present study, we cannot rule out the influence of factors such as differences among heat‐curing acrylic resins made by different manufacturers, differing polymerization techniques (11, 18) and differing methods of denture management after polymerization. As regards the BA, it is reasonable to surmise that its elution volume when the denture is in contact with saliva in the oral cavity will be lower than that observed in the present study, since the BPO eluted from resin immersed in methanol solution decomposes into BA and MB (7).…”

Embryotoxicity and teratogenesis of orthodontic acrylic resin in zebrafish

“…Formaldehyde stood out as the sole resin component, with a substantial reduction in escape response at the lowest concentration, which suggests its considerable influence on the resin. This result implies that formaldehyde might be more toxic than MMA and warrants increased attention [ 44 ]. Effects of acrylic resin and its components on heart rate .…”

Embryotoxicity and teratogenesis of orthodontic acrylic resin in zebrafish

“…Although MMA is the main component of the resin, only the highest concentration of MMA showed a decrease in the escape response. Formaldehyde was the only component of the resin that showed a signi cant reduction of this ability at the lowest concentration, which may suggest a great in uence of this component on the resin, since it can be considered more toxic than MMA, requiring more attention [53].…”
